Quora is a question and answer website – ask a question, and the ‘crowd’ answers. Users can vote for the best answers, promoting them up the list, as well as editing other peoples answers to get the most correct response.

Quora is a continually improving collection of questions and answers created, edited, and organized by everyone who uses it. The most important thing is to have each question page become the best possible resource for someone who wants to know about the question.

Quora was launched by two former Facebook employees in June 2010, and has had tremendous growth, with millions of regular users.

Questions span an enormous range of topics – from the very prosaic to the very philosophical. What distinguishes it from other similar sites is the calibre of the people who answer -often scientists, doctors, executives, actors, academics – people who would know.

Rule: When I arrive home from work, the very first thing I tell my wife is the best thing that happened that day.

No exceptions. No complaining. Just the best thing that day, even if it was just a good cup of coffee. This had the effect of starting our evening off on a positive note and it changed our relationship.

Other high scoring answers – get more sleep, exercise, and assume positive intent by others.
